LOOK - Look at them!

Does anyone know how to get the expander out of an ancient Look fork (HSC 4)?

Have you tried putting the bolt back in and giving it a little tap on the head?

Thanks, that did indeed do the trick after I worked up the courage to hit it hard enough. I’m not sure how best to go about getting the split ring out now.

Edit: turns out wiggling it out with a finger works ok. What’s the recommended aftermarket compression plug to replace this one?

ancient Look fork

How ancient, is it 1", or 9/8"?

HSC4 - 9/8"

Yeah, 1 1/8”. Full frame pictured. I bought it in a moment of profound weakness but it might be fun I suppose. Though it does have this slight ‘ring of death’ on the steerer, which is very shallow (won’t catch a fingernail) but is there. Not great obviously but how concerned should I be?

I'd used to bond a custom made long knurled aluminum sleeve with a tapped hole (for the stem cap compression) some distance from the top of the fork into used older carbon forks.
Bit over engineered, but I still have all my teeth. :)

Oh hey, I have one of those forks! Scored it for nothing - it had been junked, presumably had an incident on a roof rack; one dropout was severely bent. Bent it back, which required heaps of force, and then rode it for years.

My verdict - despite weighing fuck-all, these are tough as nails. Nice shape, too.

Wouldn't be concerned at all about the shiny ring from the headset collet.
